    Abstract: Electrohydraulic lithotripters comprising a plurality of electrohydraulic probes are disclosed. Each probe of the plurality of probes comprise a first electrode and a second electrode positioned at a distal end of the probe such that when the probe is discharged, an electric arc between the first electrode and the second electrode produces a shockwave that radiates from the distal end of the probe. A first probe and a second probe of the plurality of probes may be configured to discharge simultaneously or sequentially.

    Abstract: A multi-modulus probe design and assembly are disclosed. In one implementation, the system may include a stiffening element extending along at least a portion of a length of a lumen containing electrical wires for electrodes used in an Electrohydraulic Lithotripsy (EHL) probe. The stiffening element may be contained within the lumen of the probe or may extend along an outside of the probe.

  • Patent number: 11583641
    Abstract: Gas recirculation systems for use in endoscopic surgical procedures including a gas recirculation pump are disclosed. The gas recirculation pump may work in conjunction with an insufflator used to inflate a patient's peritoneal cavity during surgery. The gas recirculation system may recirculate a high flow rate of gas from and to the patient while filtering particulate matter out of the gas and while maintaining an adequate moisture content in the gas. The gas recirculation pump may include a disposable pump cartridge releasably connected to a pump motor. A controller may detect a fault or safety condition in the gas recirculation system based on the load placed on the pump motor.

    Abstract: Gas recirculation systems for use in endoscopic surgical procedures including a gas recirculation pump are disclosed. The gas recirculation pump may work in conjunction with an insufflator used to inflate a patient's peritoneal cavity during surgery. The gas recirculation system may recirculate a flow of gas from and to the patient, based on a detected amount of smoke in the gas, while filtering particulate matter out of the gas and while maintaining an adequate moisture content in the gas. A controller may adjust the speed of a pump motor based on the detected amount of smoke, and may also open a suction exhaust path to vent gas and smoke if the amount of smoke detected exceeds a threshold.
